What is fire short answer?

Fire is a chemical reaction in which energy in the form of heat is produced. When forest fuels burn, there is a chemical combination of the oxygen in the air with woody material, pitch and other burnable elements found in the forest environment. This process in known as �Combustion. Fire begins with ignition.

How fire is useful to us?

Fire is one of the most important forces in human history. But at the same time, fire is extraordinarily helpful. It gave humans the first form of portable light and heat. It also gave us the ability to cook food, forge metal tools, form pottery, harden bricks and drive power plants.

What is your fire?

Fire is the visible effect of the process of combustion – a special type of chemical reaction. It occurs between oxygen in the air and some sort of fuel. The fuel must be heated to its ignition temperature for combustion to occur. The reaction will keep going as long as there is enough heat, fuel and oxygen.

How dangerous fire is?

Most people who die in fires die from the toxic gases, thick black smoke, and lack of oxygen. In a fire, breathing even small amounts of these toxic elements can disorient someone, causing them to pass out. Remember smoke detectors save lives. The time to react to a fire/ smoke alarm is when it first goes off.

What is effect of fire?

During a home fire, there’s an increased level of carbon monoxide and carbon dioxide as well as damaging levels of chemical and thermal irritants. These irritants can permanently damage a person’s or animal’s respiratory system and cause death.

What are the 5 causes of fire?

The most common causes of house fires

1. Cooking equipment. Pots and pans can overheat and cause a fire very easily if the person cooking gets distracted and leaves cooking unattended.
2. Heating.
3. Smoking in bedrooms.
4. Electrical equipment.
5. Candles.
6. Curious children.
7. Faulty wiring.
8. Barbeques.

What is the reason of fire?

For a fire to start it needs a source of ignition, a source of fuel and a source of oxygen. For example, if a smoker falls asleep with a cigarette still lit, and sets fire to the sofa, the cigarette is the source of ignition, the material on the sofa is the source of fuel and the air is the source of oxygen.

How can we protect fire?

Top Tips for Fire Safety

1. Install smoke alarms on every level of your home, inside bedrooms and outside sleeping areas.
2. Test smoke alarms every month.
3. Talk with all family members about a fire escape plan and practice the plan twice a year.
4. If a fire occurs in your home, GET OUT, STAY OUT and CALL FOR HELP.

How do fire start?

Fires start when a flammable or a combustible material, in combination with a sufficient quantity of an oxidizer such as oxygen gas or another oxygen-rich compound (though non-oxygen oxidizers exist), is exposed to a source of heat or ambient temperature above the flash point for the fuel/oxidizer mix, and is able to …

What are the 4 types of fire?

Classes of fire

• Class A – fires involving solid materials such as wood, paper or textiles.
• Class B – fires involving flammable liquids such as petrol, diesel or oils.
• Class C – fires involving gases.
• Class D – fires involving metals.
• Class E – fires involving live electrical apparatus. (

Can fire kill without burning?

Fire uses up the oxygen you need and produces smoke and poisonous gases that kill. A fire’s heat alone can kill. Room temperatures in a fire can be 100 degrees at floor level and rise to 600 degrees at eye level. Inhaling this super-hot air will scorch your lungs.

What fire needs?

Oxygen, heat, and fuel are frequently referred to as the “fire triangle.” Add in the fourth element, the chemical reaction, and you actually have a fire “tetrahedron.” The important thing to remember is: take any of these four things away, and you will not have a fire or the fire will be extinguished.

What is tetrahedron of fire?

A tetrahedron can be described as a pyramid which is a solid having four plane faces. Essentially all four elements must be present for fire to occur, fuel, heat, oxygen, and a chemical chain reaction. Each of the four sides of the fire tetrahedron symbolise the Fuel, Heat, Oxygen and Chemical Chain Reaction.

Is smoke more dangerous than fire?

Fire and smoke are a deadly duo. However, smoke has more tricks up its sleeve. Most indoor fire deaths are not caused by burns, but by smoke inhalation. Smoke leads to disorientation and clouds your vision, making escape difficult.

How hot is an electrical fire?

Why fire gases are dangerous?

Why is Smoke So Dangerous? Smoke contains many toxic gases. We now have plastics and other petroleum-derived materials that produce these toxic gases. Carbon monoxide is a simple asphyxiant, meaning it binds with the hemoglobin, the protein of the red blood cells, so it no longer can carry oxygen throughout the body.

What chemicals are in fire smoke?

All smoke contains carbon monoxide, carbon dioxide and particulate matter (PM or soot). Smoke can contain many different chemicals, including aldehydes, acid gases, sulfur dioxide, nitrogen oxides, polycyclic aromatic hydrocarbons (PAHs), benzene, toluene, styrene, metals and dioxins.

Is Smoke from fire bad for you?

The biggest health threat from smoke is from fine particles. These microscopic particles can penetrate deep into your lungs. They can cause a range of health problems, from burning eyes and a runny nose to aggravated chronic heart and lung diseases. Exposure to particle pollution is even linked to premature death.

How can we prevent fire smoke inhalation?

Keep windows and doors closed. Run an air conditioner, but keep the fresh-air intake closed and the filter clean to prevent outdoor smoke from getting inside. If you do not have an air conditioner and it is too warm to stay inside with the windows closed, go to a designated shelter away from the affected area.

How can we prevent smoke inhalation?

Stay indoors, with doors and windows closed. Avoid strenuous activity and exercise. If possible, run an air-conditioner on the “recirculate” setting. Maintain your air conditioner by changing the filter when recommended.

What is the treatment for smoke inhalation?

A number of treatments may be given for smoke inhalation. Oxygen is the mainstay of treatment. Oxygen may be applied with a nose tube, mask, or through a tube down the throat. If the patient has signs and symptoms of upper airway problems (hoarseness), they will most likely be intubated.

How do you remove smoke from your lungs?

Ways to clear the lungs

1. Steam therapy. Steam therapy, or steam inhalation, involves inhaling water vapor to open the airways and help the lungs drain mucus.
2. Controlled coughing.
3. Drain mucus from the lungs.
4. Exercise.
5. Green tea.
6. Anti-inflammatory foods.
7. Chest percussion.

What happens if you inhale smoke from fire?

Inhaling harmful smoke can inflame your lungs and airway, causing them to swell and block oxygen. This can lead to acute respiratory distress syndrome and respiratory failure. Smoke inhalation commonly happens when you get trapped in a contained area, such as a kitchen or home, near a fire.

Can you recover from smoke inhalation?

Topic Overview. It is common to cough for a few minutes after breathing in smoke or fumes from a fire. Your breathing should return to normal within a short period of time, about 30 minutes.
